STEERING MECH NISM FOR VEHICLES.

Application fi1edApri122, 1914. Serial No. 833,366.

. lated to levers connected with the usual automobile axles, pivoted on vertical axes. There are two levers,one of thej levers being of the first class and the other lever beingof the third class so that. with the rotation of the rod in one direction, one of the axles will bemovedrearwardly as the other axle is moved forwardly.

Additional objects of the invention will appear in the following specification in which the preferred form of my inventionis disclosed. Y

In; the drawings similar-referencecharac ters refer to similar which I r v 1 Figure 1 is a plan view' showing my invention; Fig. 2 is a front view of Fig. 1; Fig. 3 is a fragmentary sectional view showing the connection of one of the levers with the nut which meshes with thethread on the rod; and Fig. 4 is a fragmentary sectional view showing the means for connecting the levers and the arms on the axles with the links which connect the said levers with the said arms. By referring to the drawings it will be seen that a rod 5 is disposed longitudinally parts in all the views in of an automobile and over the automobile engine 6, thesaid rod 5 having a thread 7 i with which meshesthe nut 8, this nut-8 hav ing studs 9 and 10 which are disposed in the slots 11 in the levers 12 andi13. The lever 12 is fulcrumed to a stud 14, this stud 14 extending inward from a standard 15 which is supported by the automobile frame 16. Arms 17 which are secured to thestandard 15 are connected with the automobile engine 6 for stiffening purposes. The lever 13 is fulcrumed to the stud 1 8 which extends inwardly from the standard 19, this standard 19 being secured to the automobile. frame and having arms 20 which are secured tothe automobile engine for stiffening purposes.

' The lower end of the lever 12 is articulated third class,

bearing claim as new and to the rearterminal of a link 21, the forward terminal of this link 21 being articulated .to' the curved arm 22 which is secured for r0 tating with the axle 23; The lower end of Specificationof Letters Patent. Patented 19 8 191 5;-

the lever 13 is articulated to-the rear of the 1 link-24, the forward end of this link 24 being articulated to the curved arm 25 which issecured for rotating with the short axle 26. It willbe seen that the lever 12 is of the first class, while the'lever .13 is of the and that with thefrotation of the- I rod 5 in one direction, one of the axles-will be moved rearwardly while the other short, 2

' axle is moved forwardly.

A steering wheel 27 is secured to the rear of the rod 5, this rod 5 beingjournaled. in

bearings 2 8 and 29. .The lower ends of the levers l2 and 13 having bearings 30 in which are ournaled the studs 31, these studs 31 having bearing knobs 32whichare disposed in openings. 33 in bearing members 34, the

knobs 32 being held in the openings I by the plugs 35 which are in turn held in. place by the-pins 36. The links'2l and 24 have threaded rear terminals 37 which mesh in threaded openings 38 in the bearing members 34, nuts 39 also meshing with the threaded ends 37 of the links 21 and 24, and engaging the bearing members 34 for lock- The curved arm 22 which connects the forward end ofthe link 21- with the axle 23 is bent around the rear of the axle while the curved arm 25 which connects the for threaded and mesh in threaded openings in the bearing members 40 and 41,-. these bearing members 40 and 41- having openings in which are disposed bearing knobs similar to the bearing knobs 32 shown in Fig. 4 of the drawings, these bearing knobs being held in place by the same -means*as the bearing knobs 23as shown in the said. figure of the drawings, and having studs similar to the,

7, ng the links to the said bearingmembers. v istuds l31, these studs being journaled in bear ings' in the arms 22 and 25. The axles 23 and 26 have the usualrearwardly extending arms 42, a connecting rod 43 being articulated to the said arms 42-. i

Having thus :1 described my invention desire to secure by Letters j Patent: V

1. In combination with an" automobile having a frame, an engine and axles pivoted on vertical axes, a threaded rod disposed over the engine, hearings in which the rod is journaled, a lever'disposed at each side of the engine, a nut meshing with the thread on the rod, and articulated to the levers, two standards secured to the frame and one extending upwardly adjacent each of the levers one of the levers being pivoted to the adjacent standard above the horizontal plane of the nut and the other lever being pivoted to the other standard below the horizontal plane of the nut, an arm on each axle and links connecting the lower ends of the levers with the arms. I

2. In combination with an automobile having a frame and axles pivoted on vertical axes, a threaded rod disposed over the engine, bearings in which the rod is jour naled, a lever disposed at each side of the engine, a nut meshing with the thread on the rod, means connecting the nut with the levers for operating the latter, one of the Copies of this patent may be obtained for five cent levers being fulcrumed above and the other lever being fulcrumed below the horizontal plane of the nut, and means connecting the levers with the axles for operating the latter.

3. In combination with an automobile having an engine and an axle pivoted on a vertical axis, a threaded rod disposed over the engine, hearings in which the rod is journaled, a lever disposed at one side of the engine, a nut meshing with the thread on the rod, means connecting the nut with the lever for operating the latter, and means connecting the lever with the axle for operating the latter. t

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
